Incisional adenocarcinoma after intracranial metastasis resection.

Skin and subcutaneous secondary tumors are unusual, especially in cases of colonic adenocarcinoma. They usually signify disseminated metastases. A rare case of an isolated incisional tumor after resection of a metastasis to the cerebellum is presented. The pathophysiology and management of such an event is discussed. The clinical setting suggests that this occurrence represented the result of microscopic deposits of neoplastic cells in the wound rather than hematogenous spread.
